Question

The measure of three angles of a triangle are in the ratio 1 : 2 : 1. Find the measures of these angle

Answer 1

Answer:

1x, 2x and 3x

.

We can equate 1x, 2x and 3x

to 180°.

So, the equation that we get is:-

1x + 2x + 3x = 180∘

We shall now solve this equation.

1x + 2x + 3x = 180∘6x = 180∘x = 1806x = 30∘

Answer 2

Answer:

since angles are ratio we can take them as x, 2x, x

total = x+2x+x = 4x

angle sum of triangle = 180

4x = 180

x = 180÷4 = 45°

so the angles are 45°,90°,45°
